An Analytical Method for Fast Optimization of Multireservoir Hydropower Systems Operations Considering Risk‐Return Tradeoffs

open access: yesWater Resources Research, Volume 61, Issue 6, June 2025.
Abstract Long‐term multireservoir operations optimization is challenging for existing optimization methods such as stochastic dynamic programming (SDP) and implicit stochastic programming (ISP) suffering from excessive computing time requirements. More difficult is to tackle a risk‐based optimization problem and provide an efficient frontier of the ...

Habitat conservation plans under the endangered species act: A comprehensive three‐decade analysis

open access: yesConservation Science and Practice, Volume 7, Issue 6, June 2025.
Habitat Conservation Plans (HCPs) outlined in Section 10(a)(1)(B) of the ESA have emerged as crucial instruments for harmonizing conservation and development needs. Yet, despite being established for over 30 years, the HCP program's impact remains inadequately understood.

Green Screening: Firm Environmental Strategy Amidst Policy Implementation Uncertainty in the European Union

open access: yesJournal of Management Studies, Volume 62, Issue 4, Page 1450-1490, June 2025.
Abstract We examine how firms can strategically respond to policy implementation uncertainty by screening communication exchanges between policy‐implementing agencies and their policy‐formulating political principals. These exchanges can be viewed as a signal of the agencies’ commitment to policy implementation. The costlier the agency's communication,
